The Winkler Evangelical Mennonite Mission congregation in Winkler, Manitoba began services and formally organized in 1937. The first building was occupied in 1937, with subsequent building programs in 1954 and 1985. I.P.F. Friesen and George Froese are considered the founding leaders of the group. The congregation originated through division from Sommerfelder Mennonites over its desire for revivalism.

The congregation was originally known as the Rosenbach church; it moved to Winkler in 1942. Membership records prior to 1976 were destroyed in a house fire.

In 1985 there were 417 members; in 2000, 626. The congregation has been affiliated with the Evangelical Mennonite Mission Conference since 1937. The language of worship is English and German; the transition from German occurred in the 1960s.
